That's a simplistic interpretation (as is mine). Without studying the numbers, the compensation of executives at various levels, the terms of employees, etc. it's impossible to say this business couldn't have continued to run and honored old contracts and satisfied new demands.
It's true that there's often a disconnect in how much unions demand and how much the rest of the labor market demands, and it can lead to businesses preferring to hire in non-union areas (making areas with strong unions suffer economically). I'm not entirely convinced that's the best outcome for everyone (everyone in the city, state, country, world), since it leads to employers holding a disproportionate amount of the power (the corporation becomes the only organized, powerful, force in the negotiation), and employee compensation consistently being pushed downward, while executive compensation often skyrockets. I'm pretty libertarian, so I like market forces, but I think we're seeing evidence that not having some kind of force that opposes corporations having disproportionate power leads to stagnant wages (not keeping pace with inflation), more reliance on government services (when an employer doesn't pay for any benefits, the employees end up relying on various government services for those necessities like healthcare), and a bigger disparity in power. Corporations and states end up having all the power, while individuals (those not lucky enough to have money and influence) end up getting pushed around.
If executives are receiving massive pay increases (which is what happened at Hostess; 300% pay raise, apparently), while the ship is sinking, I'd say there's a lot more than mere market forces at work. I think greed plays a role, too. In a company with some folks making millions, while others are asking for a $1/hour raise, I'm not sure I'm willing to call it merely market forces at work.
